REDOX Silicone Oil Breather Hose - Peugeot 505 Turbo Injection (1983-1989)

What is an oil breather hose?

The oil breather hose is a critical component of the engine crankcase ventilation system. Its role is to channel oil vapour produced inside the engine back into the intake manifold, where it is burned off during combustion. On a turbocharged engine such as that fitted to the Peugeot 505 Turbo Injection, this hose is exposed to particularly high thermal and mechanical stress, generated by both the turbocharger and the engine itself.

The REDOX hose is made from reinforced silicone, a material that remains supple and airtight over time. In contrast, the original rubber hoses fitted to these vehicles are now over 35 years old: they harden, crack, and eventually leak oil vapour. The REDOX silicone replacement solves this problem definitively, with a direct-fit design requiring no modification.
